Mitsubish MV2400s EDM SERVO ALARM Reoccurring

i have a 2014 Mitsubishi MV2400S Wire EDM Machine that as a reoccurring Servo Alarm in the Y axis. it doesn't happen all the time but about every other week or so i have this issue, its always the Y axis, the irritating part about it is my wire path is well over .600 away from the table edge and it continues to throw this alarm every so often.

i have changed the battery's for all the servos. i have made sure the machines stays clean and no obstructions. Just trying to see if there is anything else i can look at to stop this from happening, we are trying to do overnight runs and about once a week ill have this same issue where it says sequence error, servo alarm S01 Y axis.

i have talked with service guy about this but his response is always that you must have hit or collided with something. but i know that is not the case.

We have a 2015 MV1200S. Having same problem. When machining servo kicks out when I'm still 3/8 away from limit in Y. If I manually move in Y it will hit limit and actually bounces back. I believe the bellow on the arm is causing it. Been trying to blow air into it while submerged to loosen up crud. Can not find any info on replacing and I'm sure Mits will charge a fortune. Any help on replacement?

It is the bellows causing the issue. Remove the left side cover for the seal plate as well as the sheet metal cover next to it. Jog the machine near the -X limit. Now you should be able grab the bottom of the bellows to break up the crud. Have another person blast water into the gap between the lower arm and the bellows at the same time to flush it out. The person doing the water can also jog in Y at the same time to help.
